Absolutely avoid the braking system

The first one I ordered leaked. The second one I ordered also leaked, I don't even feel like returning the second one to get my money back. waste product.

Pros
  • Worth the money
Cons
  • Ugly packaging

Fits but does not come with pumpable fittings

Fits perfectly on my 92, NA miata, you have to loosen the banjo to tilt it properly with the hose. Too bad it didn't come with venting hardware. So I used the 2 person way. there is no more leakage and the pedal is tight again.

Pros
  • A dream come true
Cons
  • Upgrades

A small plastic threaded bolt for venting was not included.

but is missing the plastic thread screws needed to seal during the bleed process. The instructions clearly state to use the plastic thread screw that comes with it, but they weren't provided, now I have to go to the store and find equipment to connect the lines. Thanks for nothing.

Pros
  • New to my collection
Cons
  • Arrived on time for the old

Perfect replacement for OEM master cylinder.

I installed this replacement master cylinder on my 1995 Miata. It was easy to install by following the instructions that came with the master cylinder and watching a YouTube video to prove it. The quality was excellent and I am very happy with the result. It saved me over $300 doing it professionally.

Pros
  • Feel Good
Cons
  • Ratio Set

1990 Mazda Miata: Brake System

1990 Mazda Miata My old brake lever was leaking a bit and the whole cylinder was starting to rust a bit on the outside. I replaced the whole thing, took a couple of hours, you need 10mm wrench to take it off. I had to remove the stock plastic air intake to make room for the slow removal and tightening of the brake lines. Don't forget to bleed all 4 brakes when replacing. No brakes = no fun. Safety first.

Pros
  • Acceptable
Cons
  • Minor
